This hole serves to for a blow, Fig. 5, same as Fig. at, withthe reduce the weight of the plunger and at the awl driven, the peg outoff and moved under same time forms a pocket which carries and thedriver readyfor the continuation of the guides the raisin -spring BCentral with the stroke to withdraw the awl and drive the peg hole Bthrough two of the sides of the plun- 50 Fig. 6, same as in Fig. at,except that the parts ger B are the slots 13 wide enough to allow :00

the bolt A to pass freely through and long enough to'allow the desiredreciprocation of the plunger B. \Vithin the hole 3 is the raising-springB with its lower end resting upon the bolt A and when the top of theplunger is closed by the cap 13 the spring acts against the inside ofthe cap and raises the plunger.

From the foregoing it will be seen that to remove the awl or driver fromthe machine it is only required to take off the cap B and withdraw thebolts A and A, when all parts of the machine can be quickly reached.

To the lower solid end of the driver-plunger B are secured thepeg-driver B a wedge or cam 13 for operating the feeding device, and

the pin 13 for operating the swinging lever D.

The awl-carrier C is also rectangular in form and when in the machineone of its sides contacts with and slides against one of the sides ofthe driver-plunger B, as shown by Figs. 4, 5, 8, and 9, the awl C andpeg-driver B beingsecured to these contacting sides, so that they willalso contact and slide upon each other, as shown by Figs. 14 and 15.This awlcarrier is operated by the driver-plunger so that it will makeone full reciprocation and drive and withdraw the awl when saiddriverplungeris descending by the following attach ments andconnections:

Pivotedto the upper end of the awl-carrier C at C is the pawl having thedownward extension C against which the spring 0 operates to press theend of the pawl toward the driver-plunger, as shown by Figs. l and 8. Atooth or notch is formed on the driverplunger at B, so that it willengage with the end of the pawl 0 when said plunger is raised to itshighest position, and as the plunger descends it moves the awl-carrierdown and drives the awl into the stock.

There is formed upon or attached to the part A of the casing thestationary cam A which engages with the downward extension 0 of the pawlC and which completely disconnects the upper end of the pawl C from thetooth B when the awl-carrier has been moved down the proper distance andleaves the various parts in the position, shown by Fig. 5, from whichpoint the continued descent of the driver-plunger withdraws the awl fromthe stock by the following mechanism:

In a suitable recess formed in the main part of the casingA back of theplunger and awlcarrier there is hung upon a part of the bolt A thecompound swinging lever D, as shown in Figs. 4, 5, 6, 7, 8, and 9. Thislever is so shaped that as the driver-plun ger moves down from theposition shown by Fig. at to that shown by Fig. 5 the pin B fixed in andmoving with said plunger, will not change the position of the lever. Asthe descent of the driver-plunger continues below the position of Fig. 5the pin B engages with the working face of the lever D and swings it tothe left. When the driver-plunger has nearly reached its lowestposition, the lever D has been swung to its extreme limit'of motion.This motion of the lever D is transmitted to its upper extension D,which engages with the roll 0, which is connected to the awl-carrier bythe pin G and raises the awl-carrier and withdraws the awl from thestock. There is also a downward extension D from the lever D, which asthe driver-plunger is ascending engages with the pin 13 and swings andholds the lever D to its extreme limit of motion to the right ready foranother descent of the driver-plunger. To give the pin 0 fixed in theawl-carrier 0, suitable stability to resist the strain of raising theawl-carrier, the slot A is formed through the main part of the casing Aand the outer end of the pin 0 is flattened to slide therein, as shownby Figs. '7 and 8.

The throat of the machine E has attached to or formed upon it thedovetail slide E, which is fitted to the groove A of the casing A, andthis throat is secured in position by the bolt A which passes throughthe hole E The guideway for the peg-wood, as shown by Figs. 3, 11, and16, is placed so that the line of travel of the peg-wood through ittoward the driver is at right angles thereto. From. the inn er end ofthis pegwood the pegs are sheared and then moved by the swinging shear Finto the throat. The shear F is se cured to the swinging arm F, whicharm is hung upon the head of the bolt A by the pin F and the arm F isconnected to the awl-carrier C by the link F and proper pin connections,as shown by Figs. 1, 2, l, 5, and 6. As the awl-carrier moves down a pegis cut from the strip and moved into position to be driven, and when theawl-carrier moves up the peg-shear is swung back, so that another lengthof peg-wood can be moved forward by the feed-pawl E to be in turn cutoff. The swinging part of the shear cuts against the stationary shear Fsecured in the bottom of the guideway for the peg-wood, as shown by Fig.7. To hold the swinging shear up to its work and also to form a path forthe peg to swing in while moving into position to be driven, there issecured to the throat the L-shaped piece E Figs. 1, 2, 4, 5, 6, and 10.The peg-wood is fed up to the shears by the scratch feed-pawl E Figs.10, 11, 12, and 13, which is pressed forward by the spring to feed thepeg-wood and pressed back to take a fresh hold thereon by the wedge orcam B, which at the proper time passes down through the, hole E formedin the throat for that purpose and so positioned that the cam B justclears the top of the pegwood. The cam B is made of such length that itwill not move back the feed-pawl E until the preceding peg has beendriven sufficiently far into the work to be withdrawn from the nozzle Gwhen it is moved from the place where the machine was operated.

The peg-wood feed-pawl E is hung under the guideway upon the pin E andis provided with the slot E which allows it to have the requisitemotions, and the spring E acts upon the pawl in such a manner that itserves to press the points of the pawl up into the peg-wood as well asto move it forward. The retainer-pawl E is hung upon the pin E so thatits point is in contact with the peg-wood about the width of one pegback of the place where the points of the feed-pawl E will engage withsaid peg-wood, and the spring E presses the point of this retainer-pawlup into the peg-wood and prevents backward motion thereof when the cam13 is operating.

After the peg has been sheared and moved under the driver it is held inposition by two adjoining sides of the throat, the face of the shear,and one side of the awl, with the end of the driver just in contact withits head, as shown by Fig. let. IVhen the continued descent of thedriver has moved the peg a short distance down, the awi commences tomove up and the peg is carried into the nozzle of the machine, where itis guided by the two opposite sides of the nozzle G, on one side by theawl and on the other side by the registerpoint G, hung upon the pin G 14and 15. A spring G secured to the under part of the throat E by thescrew G, holds the register-point up to the side of the awl, until thepeg, pressing between the awl and registerpoint, moves said peg over toreach the hole made by the awl. When the point of the peg has reachedthe stock into which it is to be driven, the awl is nearly withdrawnfrom the stock and the register-point has moved the end of the nozzle Gover the hole just made by the awl and into which the peg is thendriven, as shown by Fig. 15. This arrangement of parts of thepeg-delivery mechanism causes the peg to be fairly driven no matter atwhat inclination the operator may hold the peg-driving machine.

Having thus described our invention, its construction and mode ofoperation, we claim and desire to secure by Letters Patent of the UnitedStates 1. In ahand peg-driving machine, the combination of easingcarrying and guiding suitable awl and peg driving mechanism consistingof two parts connected by dovetails, a

swinging lever pivoted between said parts, and a bolt holding said partsfixed in position, and upon which said lever is pivoted substantially asshown and described.
